THILL TUG.

EPECIFICATION forming part of Letters Patent No. 358,785, dated March 1,1887.

Serial No. 208,742. (No model.)

which the following is a specification, refer-' ence being had thereinto the accompanying drawings.

Figure 1 is a perspective view of the de vice 5 Fig. 2, plan views ofthe metal faceplate, showing front and back; Fig. 3, a plan of thecentral stiffening metal washer; Fig. 4, a horizontal or cross sectionthrough the con- 1 ter of the device; Fig. 5, a plan view of the strapforming loop or keeperfor end of the strap from back-band,also of one ofthe screws which secure the parts together; Fig. 6, a detail in planshowinghow the ends ofthe tuck- 23 loop are secured.

This device belongs to that class known as thill-tugs and the noveltyconsists in the construction of the several parts and in theircombination, all as will now be more fully set 2 5 out and explained,reference being had to the accompanying drawings.

In the drawings, A denotes the parts through which the thill passes, and13, attached to the part A, the buckle whereby said part is se cured tothe harness. The part A consists of the exterior metallic rims,(), oneon each side, the washers D, the central metallic washer, E, and theexterior strap, F, which passes entirely around the washers, itsextension fserving as additional means for securing the tug to theharness. The exterior metal rims, O, are shaped alike, and each isnearly circular at the body, and has ends 0 c projecting upward anddownward, respectivcl y. In these ends are holes 0. Between these rims Oand inside the loop of strap F are the washers D, made of leather,rubber, or any suitable material. I have now shown l'our of thesewashers, but may use any number, this for the most part depending on thethickness of each washer. These washers are in generalof the same shapeas the metallic plates G,and have in their ends holes (I. In these rimsthe indentations c" at the upper ends allow the rims to fit up snuglyagainst or about the lower part of the buckleframe, In the leather orrubber washer it is not absolutely necessary that there should be anyexactness of fit about the buckle'frarne, so long as free movement forthe buckle is provided for. The central metal washer, E, is of 5 5 likegeneral shape of the other washers and has holes in its ends. I designto have this washer placed so as to come about in the middle of theother washers-that is, centrally between them-thus having an equalnumber of 6Q leather washers on each side of the metal washer. Thismetal washer adds strength and firmness to the structure, The holes inthe end and the central openings in the external plates and washers,when all in place in the 6 made'up device, match or correspond; but thecentral openings in the washers are a little smaller than those of theoutside metal rims, and are finished smooth and even on the inside.When, now, the several parts are ad- 0 justed together as has been abovegenerally indicated, the screws or screw-threaded rods or bolts G arepassed through the holes at the top and bottom of the metal rims andwashers, and being set home draw the metal rims 5 toward each other, andso firmly bind together all the parts. The inner edge of the metal rimswill not touch the thill; but this passes through the one opening nowformed by the junction of the several washers, and only touches theinner edges of the washers.

It will be observed that the inner face of each metal rim is flanged atc. This gives a seat for the embracing-strap F,and thus is afforded aneat external finish; also, the inner face of each of the metal rims onone side of the rounded part is cut away at c. This affords a seat forthe ends it of the strap H,which forms the tuck-loop or keeper for theend of the strap from the back-band to rest in. The 0 ends it of thispiece H are enlarged a little at h, and extended beyond the inner edgesof 0 and thus the strap will not pull out when the metal rims arescrewed together, as has already been explained, which process clamps 5the ends of the strap H upon the edges of the openings through the tuThe ends of the strap H are rounded, so as to make a smooth finish withthe inner face of the inner edges of the washers.

Instead of screw-threaded rods to hold the several parts of the tugtogether, bolts may be used and their ends clinched or headed; but wherescrews are used there will be easier access to the several parts.

The inside of the washers,where the thill or 5 shaft passes, is sonicely made as to prevent any wear or damage to the same. This device isstrong, neat, and durable.

Having now described my invention, what I consider new, and desire tosecure by Letters IC Patent, is

1. In a thilLtug, exterior metal rims flanged on their inner faces, andhaving bolt-holes at their upper and lower ends, combined with leatheror equivalent washers and a metal 15 washer,eaeh washer having'holes atits upper and lower ends, the several parts held together byscrew-threaded rods or headed bolts and with asurrounding strap,whichalso holds a buckle, whereby said tug can be secured to 20 the harness,substantially as described.

2. A thill-tugcomposed of exterior metal rims having inner flanged edgesand washers between the same, the several parts held together by rods orbolts, as described, com- 25 bined with a strap surrounding said washersand resting on-the flanges of the said rims, substantially as described.

3. A thill-tug formed of exterior metal rims and metal and leatherwashers between the same, all held together by rods or bolts, sub- 0stantially as described.

4:- The combination of the exterior metal rims, O, indented at c intheir upper ends, the leather and metal washers D and E, and theuniting-screws,with the strap F and buckle B, 3 5 substantially in themanner and for the purposes described.

5. The combination of the rims 0, each cut away on the inner face at 0with the straploop H, having enlarged end h, the washers 0 between saidrims, and the screw threaded bolts G, substantially as and for thepurposes described.

In testimony whereofI affix my signature in presence of two witnesses.
